The Blues get their continental campaign started in Greece, with the ultimate prize of a place in next year's Champions League the main goal
Maurizio Sarri will lead Chelsea into battle in Europe for the first time on Thursday when they take on Greek outfit PAOK in their first game of the Europa League.
The Blues are competing in UEFA's second-tier club competition this term after failing to secure a Champions League finish in the Premier League last term.
They have been drawn alongside Belarusian side BATE Borisov and Hungary's MOL Vidi as well as PAOK and will be aiming to get off on the right foot with three points.
